No need to frame it tight like that, so I fixed it. That's all it is, really.
I use both DaVinci Resolve and Blender, both of which benefit from computational grunt; the more the better.
But I am a Mac user so that's why I opt for the most flexible and powerful Mac that makes sense to me. Even if these software are available on both Windows and Mac, no advances in the 'general computer components world' matter unless they are relevant for Macs.
Nothing would make me switch to Windows the way its developed today. I'm not principally against it though. If Microsoft decided to make a truly professiional OS, I guess I would consider it. But it would take a fundamental shift in priorities.
I'm curious as to what your definition of "professional" OS is. Having used both myself (quite extensively), I can say that both have their own massive pros and cons, which makes it a bit of a wash for me.
